焦莉波4376接触器的触电有哪几种?分别是什么?分别有哪些作用?对应的图形,文字符号分别是 -
薄殷蒲19363465678 ______ 接触器分为交流接触器(电压AC)和直流接触器(电压DC),它应用于电力、配电与用电.接触器广义上是指工业电中利用线圈流过电流产生磁场,使触头闭合,以达到控制负载的电器. 在电工学上,因为可快速切断交流与直流主回路和 接触器(图1) 可频繁地接通与大电流控制(某些型别可达800安培)电路的装置,所以经常运用于电动机做为控制对象﹐也可用作控制工厂设备﹑电热器﹑工作母机和各样电力机组等电力负载,接触器不仅能接通和切断电路,而且还具有低电压释放保护作用.接触器控制容量大,适用于频繁操作和远距离控制.是自动控制系统中的重要元件之一. 在工业电气中,接触器的型号很多,电流在5A-1000A的不等,其用处相当广泛.
